I finished the connecting of wires on my 94. I was finsihing up the pass. side by the long tube headers. I connected the O2 sensor, did the knock sensor, coolant sesnor and starter wires. There is one more left and I do NOT know where it connects to?

Its got 4 connections ( female) that plug into it. It looks kind of like the O2 sensor. Where does this plug into?..Its lurking around my flywheel/back side of block...I can take a pic if no one knows..

Without looking I think maybe the AC pressure switch. I'll go take a gander and see if it jars my memory.

On the passenger side of a 94 vette you have two o2 sensor plugs.If you have long tube headers,you only need 1 hooked up.From the factory the passenger catalytic converter had two o2 sensors.

This is what I was thinking. That O2 rear sensor was the "get ready for OBD2" platform. The 94 is OBD1 and does not really utilize the rear sensor in it's OBD2 future environment.

I believe the 96 as it is OBD2, has the 4 O2 sensors and has the OBD2 platform with the "P" error codes.
